Double-Balloon Enteroscopy (DBE)

It is normally performed following a finding in the small bowel after a video capsule endoscopy or scan, in order to treat or biopsy. Your consultant will access the small bowel through your mouth or rectum. You'll be asleep for the duration, under general anaesthetic.

The technique involves the use of a balloon at the end of an endoscope (a flexible tube with a high-quality video camera) and an overtube. The tube is passed through the small bowel with the balloon inflated to grip sections of the intestine and shortened by folding it over the endoscope. The test can take up to 2 hours in the endoscopy suite.

You will need to be on a low-fibre diet and increase your fluid intake from two days before the procedure. You will need to be on a liquid diet (no solid foods) from one day before the procedure.

You will also need to take a laxative. You will be able to drink water right up until your procedure.

You should be able to return home after around one hour, depending on the rate of your recovery. You will be unable to drive so should have a friend or relative pick you up so you can be escorted home.

You will be given post-procedure instructions and contact information should you have any questions.
